BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an exercise device, and more particularly to portable exercise device.

2. Description of the Related Art

Currently, a typical exercise device, as shown in FIG. 16 and FIG. 17, comprises: a pad 70 with a securing base for connecting to a massaging module 80. The massaging module 80 utilizes a motor 82 to drive two driving shafts 83 and two eccentric wheels 84. The two eccentric wheels 84 are respectively disposed at two opposite ends and connected to two straps 81. The motor 82 is a double-phase motor and used for driving the driving shafts 83, and the eccentric wheel 84 utilizes an eccentric member 841 to be connected to an assembling member 842 and a bearing 843 to be disposed at two opposite ends of the driving shaft 83. The strap 81 is connected to the assembling member 842 of the eccentric wheels 84 and has an adjustable fastening section 811, and the adjustable fastening section 811 is one part of a paired buckle or Velcro.

When the motor 82 is active, the driving shaft 83 is driven to rotate the eccentric member 841 of the eccentric wheels 84, such that the assembling member 842 is drive by the bearing 843. Therefore, the straps 81 are respectively placed through the pad 70 and provide vibration movements.

However, above-mention device has following issues: 1. The massaging module 80 is required to be equipped with the pad 70, which is very inconvenient. 2. The massaging module 80 provides vibration movements to human body, which can also cause discomfort. 3. The vibration movement tends to affect the skin layer more than the muscles, which cannot provide exercising effect. 4. The pad 70 limits the length of the straps 81, which reduce the exercising effect.

Furthermore, another exercise device, as shown in FIG. 18 and FIG. 19, comprises a base, a supporting column 91 extending from one side of the base 90. The supporting column 9 is provided with a controller 92, a hook 93 respectively disposed two sides of the controller 92, and a connecting loop 94 is attached onto each hook 93. The connecting loops 94 are used for being connected to a belt 95, and an elastic strap 96 is attached at a predetermined position.

However, the above-mentioned device has following issues: 1. The exercise device is not portable, which is very inconvenient. 2. The belt 95 and the strap 96 provide vibration movements to human body, which can also cause discomfort. 3. The vibration movement tends to affect the skin layer more than the muscles, which cannot provide exercising effect. 4. The belt 95 only touches small area of human skin, which limits the exercising effect. 5. The strap 96 is attached onto the belt 95, however, the vibration movements between the two can be interference with each other which can cause discomfort to a user.

Therefore, it is desirable to provide a portable exercise device to mitigate and/or obviate the aforementioned problems.
